Hi,Everybody

1--From the scripti "python sys_analyzer_linux.py -v " I got the output

2--And ,from the scripti "sudo python sys_analyzer_linux.py -v " I got the output

--------------------------

3--sam@sam-dev:~/Downloads$ which ioc64
/usr/bin/ioc64

4--When I use the commond "ioc64 -input=22.cl -device=gpu",the log as that.
No command specified, using 'build' as default
OpenCL Intel(R) Graphics device was found!
Device name: Intel(R) HD Graphics
Device version: OpenCL 1.2 
Device vendor: Intel(R) Corporation
Device profile: FULL_PROFILE
fcl build 1 succeeded.
fcl build 2 succeeded.
bcl build succeeded.

simpleAdd info:
	Maximum work-group size: 256
	Compiler work-group size: (0, 0, 0)
	Local memory size: 0
	Preferred multiple of work-group size: 32
	Minimum amount of private memory: 0
	Amount of spill memory used by the kernel: 0

Build succeeded!

5--And , I use the eclipse Neon ,it report "please make sure to set the correct path under the Code Builder for OpenCl preference page"

6--sam@sam-dev:~/Downloads$ uname -r
4.4.0-92-generic

7--sam@sam-dev:/etc/alternatives/opencl-intel-tools$ ls
bin doc eclipse-plug-in include lib64 version.txt

I really need slove the problem in eclipse.If i miss some important thing ,please let me know .Thanks.

At last , I'm not sure about my LD_LIBRARY_PATH is good , when i use the echo commond to print it.It shows nothing.

sam@sam-dev:/$ echo $LD_LIBRARY_PATH

Uh....i don't know how to set the environment of LD_LIBRARY_PATH.when i use set it in /etc/environment as "LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu:/usr/lib64:/usr/local/lib" " .The sys_analyzer_linux will report can't find libva.so and libva.so.1.
